If y is inversely proportional to x and y = 45 when. = 20, find yif = 5. (Round off your answer to the nearest hundredth.)
If y is inversely proportional to x, it means that the product of y and x remains constant. We can write this as:
y * x = k
where k is the constant value.
Given that y = 45 when x = 20, we can substitute these values into the equation to find k:
45 * 20 = k
k = 900
Now, we can use this value of k to find y when x = 5:
y * 5 = 900
y = 900/5
y = 180
Therefore, y is equal to 180 when x = 5.
